# Ask for a change

> Open your video, write or say what you want different in **Ask**, and Montage changes the video. Each change is kept, so you can always go back.

## Ask, step by step

1. Open your video. On a computer, **Ask** is the first tab of the card on the right.
1. Write in the box: « Ask for a change… ». Say it like you would to an editor: « Cut the pause at 0:17 », « Captions bigger ».
1. Or press the mic and speak. Montage writes what it hears; press the mic again to stop.
1. Press **Enter** or the arrow to send. **Shift + Enter** starts a new line.
1. Montage works: you see the time since you asked, and « Montage is looking » around the picture when it watches a moment. Then the player shows the new version.

## What the box can add

| In the box | What it does |
|---|---|
| **+** then **Add footage** | Adds videos, music or pictures from your computer, sent with your message. |
| **+** then **From the Library** | Picks a style or a component your team saved. It shows as a chip over your words. |
| The AI model chip | Haiku, Sonnet or Opus for this change. [Choose the AI model](/docs/edit/model) |
| The mic | Speak instead of typing. |

## Every change is kept

Each change Montage makes becomes a line of the video's **History**, with a short name of what is different. You can watch any line and go back to it. [Undo a change](/docs/edit/undo)

> Montage answers one message at a time. While it works, the box waits: send your next change once it is done.

## Credits

Each change uses credits, more with a bigger model. When your credits are out, Montage stops before the change and says so; your video is safe and **Export** still works. **See the plans** shows under its answer.

## Questions

### Can I edit the video by hand?

No. Montage makes every change: you watch, ask, and comment on the picture.

### Can I add footage after the first version?

Yes. Press **+**, then **Add footage**, in the box. It is sent with your message once it is ready.

### Where are my older messages?

Ask shows the last ones. Press **Earlier** at the top to see the rest.
